BURGLAR-ALARM WIN Dow-FASTEN En.

SPECIFICATION forming part of Letters Patent No. 764,534, dated July 5, 1904.

Original application tiled August 14, 1901, Serial No. 71,877. Divided and this application filed June 10, 1903. Serial No. 160,909. KNo model.)

To all whom t Nea/y concern;

. Be it known that I, JOSEPH LYON, a citizen of the United States, residing at DaytomNlontgomery county, Ohio, have invented a certain new and useful Burglar-Alarm VVindow-Fastener, of which the following is a speciiication, reference being had to the accompanying drawings, forming a part hereof, and in which like characters of reference indicate the same parts, said invention being a part of my application, Serial No.71,877, iiled August 14, 1901, for aburglar-alarm house-protector and being now divided therefrom.

My invention relates to improvementsin burglar-alarm window-fasteners; and it consists of the means, combinations, arrangements,.and subeombinations of the various parts and means, all as hereinafter described at length and briefed in each of the appended claims.

The means best known to me at this time for accomplishing the objects of my invention are illustrated in the accompanying drawings, in which- Figure 1 is an elevation view of a portion of the upper and lower sash and their casing, va portion of the casing being broken away to disclose the parts Within. Fig.2 is a sectional plan view substantially on line .fc .fc of Fig. l. Fig..3 .is a side view of one of the windowlocking bolts in section substantially on line fr fr of Fig` 2. Fig. 4 is an elevation view, partially in section substantially on line y 1/ of Fig. l. Fig. 5 is an interior view of a portion of a house adapted to be protected and rendered burglar-proof by my invention. Fig. 6 is a sectional View from ythe left of Fig. l and omitting the alarm-bolt and its mounting mechanism. Fig. 7 is a sectional View of a portion of the meeting-rails of the sash and showing the ordinary Window-fastener.

The house or structure to be protected may have any desirable -number of windows or openings adapted to be closed by a plurality of slidable members, each of which. is provided withy the following means: Upon the top of the lower sash or near the meeting edge of one of said slidable members is secured a bearing-plate 5l, upon which is slidably mounted in any suitable manner a plate or bolt 52, provided with projections 53, to which is pivotally connected a supplemental bolt 54 at a point intermediate its ends, said supplemental bolt 54 having two branches projecting at an angle to each otheiand said pivoted connection of said supplemental bolt 54 being intermediate said branches. The branch 47 of said supplemental bolt 54 projects laterally therefrom and is adapted to cooperate with any one of a plurality of keepers mounted upon the inner face of the upper sash 55, while the branch 4S of said supplemental bolt 54 projects therefrom with its .longitudinal axis parallel with the slidable movement of said bolt 52 54 and is adapted to enter any one of a plurality of keepers mounted upon the window-casing 60 adjacent said bolt.

The keepers upon the upper sash 55 are formed of a plurality of projections or pins 56, removably secured to the inner edge of the upper sash 55 and projecting therefrom to substantially the height of the ledge 61 upon the bottom of said upper sash 55. Said projections 56 may be upon the upper and lower sides of the bolt branch 47 to constitute cach keeper, as shown for the upper keepers upon the upper sash, or but one projection 56 upon the upper side of the bolt branch 47 may constitute each keeper upon the upper sash, as shown for the lower keeper upon said upper sash.'

Each of the keepers upon the casing 60 is formed of a face-plate 62, having a keeperopening 63 therein, Figs. 1 and 6, said opening 63 being larger than said bolt 52 54 in a vertical direction-that is, in the direction of the movement of the lower sash 50. Secured to and projecting from the rear side of plate 62 are plates 64 and 65 at an angle to each other and extending into an opening 66 in the casing 60. Secured to said plate 64 is an electrical contact member 67, insulated from said plate 64, while secured to said plate 65 is an electrical contact member 68, having a projection 69 adapted to normally engage or contact with said member 67 for normally maintaining an electrical circuit. Members 67 and f 68 are substantially at right angles to each other, and member 68 is uninsulated from said plate 65 and plates 64 and 65 being integral or electrically connected together. Member 67 is mountedabove the plane of the keeperopening 63, and below said member 67 is an electrical contact member 70, having a projection or downward bend 71 extending into the plane of said keeper-opening 63 and adapted to engage with the branch 48 of bolt 54 and be moved thereby into contact with member 67 for the purpose of establishing an electrical circuit, member being secured to plate 64 by screw 72, which also secures member 67 thereto, said member 70 being insulated from said member 67, which member 67 is also insulated from said plate 64 by the insulation-disks shown. Electric-circuit wires 73 and 74 connect, respectively, with members 68 and 67, the circuit being normally closed by projection 69 of member 68 contacting with member 67 The outer end of member 68 projects into the plane of the keeper-opening 63, Figs. 4 and 6, and is curved at its outer end, (see Fig. 2 in dotted lines,) so that when the bolt 52 54 is shot into its keeper 93 it will be engaged along its side by member 68, and the curved or cam-shaped end of member 68 will cause said bolt to move said member 68 laterally and separate its projection 69 from member 67 and thus break the electrical circuit. The outer end of plate or bolt 52 is provided with an upturned outer end 75, adapted to enter the keeper-recess 63 and contact with the members 68 for keeping its projection 69 out of contact with member 67. The lateral or sliding contact on the bolt of the members 68 and 7 O dispenses with nicety, exactness, and uniformity in the shooting of the bolt and provides a safe contact unaffected by wear upon the parts or careless operation.

Should bolt 52 54 be withdrawn from its keeper-opening 63 at any time, the projection 69 will bythe withdrawal more especially of the keeper end of bolt member 52 be moved into contact with electrical contact member 67 by reason of the spring contact member 68 assuming its normal position in the plane of said keeper-opening 63, and an electrical circuit will thereby be established.

While bolt 52 54 is in its keeper-opening 63, should an entrance be attempted by lowering the upper sash 55 one of the projections 56 will be pressed downward upon the branch 47 of bolt member 54, which will cause the branch 48 of bolt member 54 within said keeplower sash 5'0 be raised to force anentrance the bolt 54 will be moved upward at its outer end 48 by reason of the fulcrum of said bolt 54 and its engagement at its opposite end 47 with one of the projections 56 of the upper.

sash, which movement of said bolt 54 will likewise move member 70 into engagement with member 67 and similarly establish an electrical circuit.` Each of the members 67 within each of said keeping-openings 63 forms one circuit-terminal, while the opposite or other circuit-terminal is branched and is composed of the members 68 and 70, either of which is adapted to be brought into engagement with the members 67 according to the movements of bolt 52 54.

Should entrance be attempted by removing a portion of the glass and withdrawing bolt 52 54 preparatory to raising the sash 50 or lowering the sash 55 preliminary to entrance, the withdrawal of bolt 52 54 will establish an electrical circuit between members 68 and 67 as heretofore stated.

The keepers in the frame or casing 60 of each window are uniform distances apart, while the keepers upon the upper sash 55 are preferably the same uniform distances apart in order to provide for ventilation by lowering the upper sash or raising the lower sash, or both, desirable distances and locking them in -said position with my improved burglaralarm window-fastener simply by the shooting oi"v a bolt for each window.

The keeping-openings 63 in each windowcasing 60 are near the upper sash 55 in order to permit their respective bolts 52 54 to enter upon one side of the sash-cord 8O for each of the lower sash 50.

The contact members 67, 68, and 7 O of each of the plurality of keeping-openings 63 for each window are adapted to and compose a single circuit with the annunciator 81 and battery or other electrical generator 82 and bell or alarm means 83, and each window is connected thereto by a separate circuit, so that each opening where an entrance is attempted to be effected may be indicated by the annunciator 8l. i

In the instance shown in the drawings the plate 51 is secured to the sash 50 by a plurality of screws 85, while the bolt 52 is slidably mounted thereon by screws 86, passing through slots 87 in said bolt 52 and embedded into plate 51, said bolt 52 being adapted to be locked in either position out of its keeperopening 63 by means of a screw 89, adapted to clamp bolt 52 to said plate 51.

Bolt 54 is provided with a cylindrical cavity 90, containing a cylindrical pin 91, preferably of hardened steel, loosely fitting said opening 90 and being loosely sealed in said opening by a plug 92, closing the mouth of said opening 90 for the purpose of preventing an opening being forced without giving an alarm by sawing off the bolt 54 and leaving the end or branch IOO IIO

48 thereof in one of the keeping-recesses 63, so that an entrance may be effected thereby without giving the alarm. Should bolt 54 be attempted to be sawed, the saw will go through the outer surface of bolt 54 and penetrate a portion of the cavity 90 and contact with the pin 91, and the saw will roll pin 9,1, and consequently the saw can gain no hold upon said pin 91, and therefore the saw will be eectually resisted and prevented from sawing through the bolt 54. Of peculiar importance is this feature, together with that of the elongation of opening 63 to permit only a limited movementl of said bolt and the sash in the direction of the travel of the window sash,

.whereby an alarm is sounded while entrance is effectually barred by the bolt 52 54,- thus giving theoccupants of the house protected by my invention ample opportunity to summon aid or otherwise prepare to resist such an invasion before an entrance is effected.

Mounted centrally upon the meeting-rails of each of the upper and lower sashes 50 to 55 'is the ordinary Window-fastener, comprising a keeper 100, having keeping opening 101 adapted to snugly fit bolt 102, movably mounted in casing 103 and adapted to be actuated by lever 104, said ordinary Window-fastener being Within view from the outside and being' deceptive to the extent that it renders an intruder less cautious and to believe that said ordinary window-fastener 100 to 104 is the only securing device for each window, and a further primary object of said ordinary window-fastener is that when each window is closed the locking of each window by means of said ordinary window-fastener, in addition to locking the same with the bolts 52 54, prevents th'e sounding of an alarm by the relative movement of the bolts 52 54 in their respective keepers, as aforesaid, until said ordinary window-fastener is either badly sprung or is broken by the attempt of an intruder to cause an entrance. Said ordinary windowfastener may be ofiany of the common constructions employed.

It will be seen that with the means or apparatus preferably employed for the purpose.

of practicing or exemplifying my invention, which means or apparatus may be departed from in many respects without departure from the spirit and scope of my invention, each of the windows when locked in any of their Ventilating positions is most conveniently set for sounding an alarm by having the end 7 5 of bolt 52 engaging the bottom of its its keeping-opening 63, and a very slight relative movement of either the sash or keeper will sound an alarm, while entrance is yet barred by the bolt 52 54 in its keeping'- opening 63 for each window.

Spring 110 between bolts 52 and 54 causes bolt 54 to engage bolt 5.2 at its end 48under normal 4conditions and prevents an alarm from being' sounded by the vibration of' bolt 54 upon its fulcrum, due to slight jars upon Y direction of the movement of said sash, av

member mounted in said keeper normally in the path of' said bolt when shot into said keeper, a second member mounted in said keeper adjacent said first member, said first and second members being adapted to engage with each other when said bolt is withdrawn from said keeper and when said sash is moved, means for sounding an alarm upon the engagement of' said first and second members, and a second bolt and keeper for said sash, whereby when said first bolt is tampered with an alarm is sounded by said first bolt and said first and second members and the house is protected by said second bolt and keeper, substantially as specified.
